Siren

This is at the bottom of the scale, where a color stops being a backdrop and the red sits underneath, felt rather than seen outright. Vista Paint files it as 1117.

11.0 on the light-reflectance scale is near the floor - this color adds shadow to a room rather than taking it away. It swallows shadow, so the room reads by its light sources and architectural lines.

This color and blues and cool greys don't get along in the same room - they sit on opposite sides of the spectrum, so pairing them tends to feel like tension rather than contrast.

Next to it, white trim reads brighter and cooler than it does anywhere else in the house - the gap in light reflectance is what does that, not the trim paint itself. If the room needs more than one wall color, keep the steps far apart: this color, then something clearly lighter for a second surface, then a bright white above. Two similar tones just look like a mismatch; three distinct ones read as a plan (about 11.0 to 48 to 85 in LRV terms).

In a small, enclosed room - a powder room, a reading nook - this can work on every wall, since there is no large floor area losing light to it. For a secondary wall, Behr Clear Pond gives a natural step up in brightness without feeling like a mismatch (roughly 46 LRV points apart).

A color this deep already reads as dramatic; a low-sheen finish lets the color carry that without competing highlights.

Switching brands, Behr No More Drama (P140-7) is the closest equivalent at delta-E 1.06, near enough for most rooms. Only 2 other-brand colors land within delta-E 2 of this one, which makes it comparatively unusual.

It is lighter than 8 percent of the Vista Paint range. This is a crowded part of the scale - 546 colors measure within a point of 11.0 - so most brands will have something close. The name is not unique: Behr P190-4 also sells a color called Siren, and it is not the same shade. Vista Paint lists it in the C codes, alongside 1,421 other colors.
